本文概述了一个框架，用于研究广义粮食系统与全球环境变化的多重相互作用，并评估受这些相互作用影响的主要社会结果：粮食安全、生态系统服务和社会福利。在构建框架时，本文探索并综合了有关粮食系统、粮食安全和全球环境变化的不同文献，连接了社会科学和自然科学的观点。这些收集到的证据证明了粮食系统的代表性，可用于确定特定地点或时间粮食安全的关键过程和决定因素，特别是环境变化的影响。它还可以分析粮食系统结果对环境和社会变化驱动因素的反馈，以及粮食系统结果本身之间的权衡。在粮食系统中，这些权衡通常发生在不同规模或级别的决策或管理之间，因此管理它们的解决方案必须针对具体情况。有了足够的经验证据，该框架可用于建立可用于不同管理或分析目的的粮食系统相互作用类型数据库。 (C) 2007 Elsevier Ltd. 保留所有权利。
This paper outlines a framework for studying the multiple interactions of broadly defined food systems with global environmental change and evaluating the major societal outcomes affected by these interactions: food security, ecosystem services and social welfare. In building the framework the paper explores and synthesizes disparate literature on food systems food security and global environmental change, bridging social science and natural science perspectives. This collected evidence justifies a representation of food systems, which can be used to identify key processes and determinants of food security in a given place or time, particularly the impacts of environmental change. It also enables analysis of the feedbacks from food system outcomes to drivers of environmental and social change, as well as tradeoffs among the food system outcomes themselves. In food systems these tradeoffs are often between different scales or levels of decision-making or management, so solutions to manage them must be context-specific. With sufficient empirical evidence, the framework could be used to build a database of typologies of food system interactions useful for different management or analytical purposes.
